Description
Technical field
The present invention relates generally to control the device of temperature, relate in particular to and control movably the preferably device of the temperature of electrical heating roller movably of electrical heating object.
Background technology
Photothermal imaging is a technology that is embodied as picture.When photothermal imaging, light-sensitive medium is exposed to form sub-image, and it can be by thermal treatment with the development sub-image.The apparatus and method that are used to implement this thermal development technology are well-known, comprise the light-sensitive medium that makes contact to picture with heated platen, cylinder or band, hot-air is blown on the medium, medium is dipped in the inert fluid of heating and makes the medium exposure under radiation energy, for example infrared ray with the photostable wavelength of medium.In these routine techniquess, the use of heated roller is particularly common.
The light-sensitive medium that is commonly used in these imaging process is known as the photothermal imaging medium, such as film and paper.A kind of photothermal imaging medium has the reductive agent of bonding agent, silver halide, organic silver salts (or other reducible photostable silver material) and silver ion.In commerce, these photothermal imaging media are known as dry type silver salt medium, comprise dry silver film.
In order accurately to heat the photothermal imaging medium of exposure, comprise film and paper, find, use electrical heating roller can obtain ideal effect.In adopting the device of this technology, cylindrical drum is heated to temperature near the desirable development temperature of photothermal imaging medium.When cylinder when its longitudinal axis rotates, the photothermal imaging medium be fixed on heated roller near.When knowing the surface temperature of heated roller, just known the photothermal imaging medium is fixed near the cylinder the roll circumference part and the rotating speed of cylinder, also just can determine the development time and the temperature of photothermal imaging medium.Usually, at the specific light thermal imaging medium that is utilized, also may be at these parameters of the incompatible optimization of applied field that adopt the photothermal imaging medium.
In order in the photothermal imaging medium, to realize high quality graphic, must keep point-device photographic parameter.Usually, circumference of the cylinder by the photothermal imaging medium can not change significantly on it.Equally, the rotating speed of cylinder or photothermal imaging medium can quite accurately be kept through the transfer rate of heated-treater.But, usually more difficult control and keep the temperature of cylinder surface.
In addition, other factors also can have influence on inaccurate processing.The photothermal imaging medium is fixed to the temperature that the degree of approach on the cylinder has been determined the photosensitive emulsion of heating photothermal imaging medium.In addition, the existence of the foreign particle between cylinder and the photothermal imaging medium can be interrupted heat on the cylinder to the flowing of photothermal imaging medium, and this will influence picture quality.
Because many factor affecting picture qualities are arranged, one of them is the temperature of development photothermal imaging medium, and the accuracy that can keep the cylinder surface temperature is important for the hot-working of photothermal imaging medium.
The temperature of cylinder depends on many factors.These factors comprise that the speed with the photothermal imaging medium of the thermal mass of the thermal conductivity of the speed of heat transferred cylinder, cylinder and thermal mass, photothermal imaging medium, processing is number (if using light sheets thermal imaging medium), environment temperature, no matter whether hot-working has just begun or be in long-time period middle period.
In addition, heated roller is widely used in multiple other materials processing application.Example comprises press polish, lamination, coating and drying.
Usually, by using the stratie cylinder that heat transferred is such.Because heated roller rotates during hot-working, and because wish during cylinder rotates, to give stratie with electrical energy transfer, thus wish can from fixed power source for example the electrical energy transfer of standard electric alternating current source line give the cylinder that moves, rotate.Can give cylinder with electrical energy transfer by using the slip ring that is connected with cylinder.
In addition, in order accurately to control the temperature of electrical heating roller, the signal controlling that should have the device of a sensing roller temperature and a response temperature sensor is applied to the device of the electric energy on the electric resistance heater.
Though temperature control technology and device are common, because of the rotation of cylinder or mobile more difficult this class technology and device of on loose impediment or rotary drum, using of object.
Have a kind of scheme and on loose impediment or rotary drum, set up all temperature sensings and control technology.Under the situation that cylinder rotates, adopt the analog temperature control technology, that is, the circuit board that accommodates mimic channel is added on the cylinder of rotation or near it, thereby allows that circuit board rotates with cylinder.Though this technology has farthest reduced to be communicated with the temperature sense information between cylinder and the mimic channel and the difficulty of control information, more difficult connection analog control circuit or change or regulate temperature or control algolithm.
The similar technique that Minneapolis city, Minnesota State Systek adopts has utilized the temperature-control circuit that rotates, and provide extraly a kind of rotary drum/control circuit sensing temperature information the communication technology and utilize cylinder that the user's of heated-treater adjusting parameter is communicated to technology on rotary drum/control circuit.The ring of a plurality of light emitting diodes is disposed in being generally on the circular figure of cylinder/control circuit one end.Single light emitting diode is positioned near near the fixed head this rotary drum/control circuit one end.Light sensor is positioned on rotary drum/control circuit on rotation axis one end.Equally, another light sensor is positioned on the fixed head.Each light sensor all is suitable for the working cycle modulated pulse group of corresponding light emitting diode on the sensing opposed member.By making every pair of light emitting diode and sensor farthest reduce interference in the light conduction with the different frequency effect.For example, a pair of can in visible spectrum, the operation, and another is to operating in infrared spectrum.
But, the Systek system is confined to read quite coarse temperature sense information.In addition, all temperature control loops all fully are positioned on rotary drum/control circuit board.Like this, the information of any embedding temperature control loop must be able to be included on rotary drum/control circuit board, thereby has limited available electric energy and selected object.
On Dec 3rd, 1996 is disclosed, the invention people has described another program for people's such as Tanamachi United States Patent (USP) 5580478.This United States Patent (USP) has disclosed a kind of via the method for the two-way infrared optical link from removable heating object to fixing microprocessor system corresponding to each Heating Zone Temperature synchronous transmission FM signal.Microprocessor then transfers back to removable heating object by bi-directional optical with the well heater control information.These signals have been controlled the electric energy that is applied on the relevant well heater via the solid-state relay that is installed in the loose impediment.
